PDF-(EBOOK)-Spacecraft Formation Flying: Dynamics, Control and Navigation

Space agencies are now realizing that much of what has previously been achieved using hugely complex and costly single platform projectslarge unmanned and manned satellites including the present International Space Stationcan be replaced by a number of smaller satellites networked together The key challenge of this approach namely ensuring the proper formation flying of multiple craft is the topic of this second volume in Elseviers Astrodynamics Series Spacecraft Formation Flying Dynamics control and navigationIn this unique text authors Alfriend et al provide a coherent discussion of spacecraft relative motion both in the unperturbed and perturbed settings explain the main control approaches for regulating relative satellite dynamics using both impulsive and continuous maneuvers and present the main constituents required for relative navigation The early chapters provide a foundation upon which later discussions are built making this a complete standalone offeringIntended for graduate students professors and academic researchers in the fields of aerospace and mechanical engineering mathematics astronomy and astrophysics Spacecraft Formation Flying is a technical yet accessible forwardthinking guide to this critical area of astrodynamics.

Used increasingly in telecommunications, scientific research, surveillance, and meteorology, satellites rely heavily on complex onboard control systems. This book explains the basic theory of spacecraft dynamics and control and the practical aspects of controlling a satellite. The emphasis is on analyzing and solving real-world engineering problems. Among the topics covered are orbital dynamics, attitude dynamics, gravity gradient stabilization, single and dual spin stabilization, attitude maneuvers, attitude stabilization, and structural dynamics and liquid sloshing. Provides the basics of spacecraft orbital dynamics plus attitude dynamics and control, using vectrix notationSpacecraft Dynamics and Control: An Introduction presents the fundamentals of classical control in the context of spacecraft attitude control. This approach is particularly beneficial for the training of students in both of the subjects of classical control as well as its application to spacecraft attitude control. By using a physical system (a spacecraft) that the reader can visualize (rather than arbitrary transfer functions), it is easier to grasp the motivation for why topics in control theory are important, as well as the theory behind them. The entire treatment of both orbital and attitude dynamics makes use of vectrix notation, which is a tool that allows the user to write down any vector equation of motion without consideration of a reference frame. This is particularly suited to the treatment of multiple reference frames. Vectrix notation also makes a very clear distinction between a physical vector and its coordinate representation in a reference frame. This is very important in spacecraft dynamics and control problems, where often multiple coordinate representations are used (in different reference frames) for the same physical vector.Provides an accessible, practical aid for teaching and self-study with a layout enabling a fundamental understanding of the subjectFills a gap in the existing literature by providing an analytical toolbox offering the reader a lasting, rigorous methodology for approaching vector mechanics, a key element vital to new graduates and practicing engineers alikeDelivers an outstanding resource for aerospace engineering students, and all those involved in the technical aspects of design and engineering in the space sectorContains numerous illustrations to accompany the written text. Problems are included to apply and extend the material in each chapterEssential reading for graduate level aerospace engineering students, aerospace professionals, researchers and engineers. This highly regarded book provides a bridge that spans spacecraft maneuvering and control techniques with associated physical fundamentals. Beginning with an examination of the basic principles of physics underlying spacecraft dynamics and control, the text covers orbital and attitude maneuvers, orbit establishment and orbit transfer, plane rotation, interplanetary transfer and hyperbolic passage, lunar transfer, reorientation with constant momentum, attitude determination, and attitude adjustment requirements. Additional topics include attitude control devices as well as automatic attitude control, orbital perturbations, and the fundamental methods of astrodynamics. A final chapter explores some special problems in this field. This treatment is suitable for advanced undergraduates and graduate students and professional engineers in astronautics. Each chapter presents relevant exercises of varying difficulty, and the text includes a section of answers to selected exercises. Pointing a satellite in the right direction requires an extremely complex system — one that describes the satellite\'s orientation and at the same time predicts and either uses or neutralizes external influences.From its roots in classical mechanics and reliance on stability theory to the evolution of practical stabilization ideas, Spacecraft Attitude Dynamics offers comprehensive coverage of environmental torques encountered in space energy dissipation and its effects on the attitude stability of spinning bodies motion equation for four archetypical systems derived and used repeatedly throughout the text orientation parameters (not limited to Euler angles) illustrations of key concepts with on-orbit flight data and typical engineering hardware, with examples of the implementation of dynamic ideas.Suitable as a text for advanced undergraduates and graduate students, this unified treatment is also a valuable reference for professional engineers studying the analysis and application of modern spacecraft attitude dynamics. The sole prerequisites are a fundamental knowledge of vector dynamics and matrix algebra. Over 250 diagrams appear throughout the text, along with extensive problem sets at the end of each chapter, 350 references (cited, interpreted, and placed in perspective to reinforce the material), and two helpful appendixes.
